It seems as if I’ve been trying to lose weight for all of my adult life. The diagnosis of type 2 diabetes only added to my desire to lose a few pounds. Lately, I seem to have hit a brick wall and am unable to lose any more. Could it be the amount of coffee I’m consuming?

Studies have shown that moderate coffee consumption is actually good for our health, including the benefits of weight loss and increased insulin sensitivity. However, too much coffee consumption can lead to weight gain and more glucose intolerance, according to an Australian study that was published in the Journal of Agricultural and Food Chemistry. It was found that consumption of five or more cups of coffee per day has a detrimental effect. It’s actually “consumption of certain polyphenols found in coffee called chlorogenic acid (CGA) (that) could prevent fat loss and lead to insulin resistance” and not the caffeine itself.

Now, before you think that there is no way you’re consuming that much coffee, consider this: five ounces is considered an average cup of coffee. The coffee mugs in my cupboard hold nine ounces. So, when I drink a “cup” of coffee I’m actually drinking two cups. Add to that our society’s penchant for coffee shops where we can buy lattes, cappuccinos, and frothy coffee drinks, we are consuming far more coffee than we realize.

Since reading this information, I’ve cut back on my coffee consumption. It seems like an easy way to see if I can lose a bit more weight and possibly help my blood glucose numbers. It also makes sense to drink coffee black, or at least without added sugar.

Do you think you could just switch to black coffee? Leave your thoughts in the comments below.
